Back in the Old Wild West, petroleum jelly emerged with the trade name, "Vaseline." It has remained unchanged for over 120 years because it's one of those all-purpose, handy-dandy products that cowboys and homeowners have found handy for everything from softening saddles to preventing rust on tools, guns and metal things of all kinds. Rub a little on your hands and you've got an invisible glove of sorts that makes dirty, messy cleanups a breeze. Rub some on your face and you've got a shiny look that protects your mug from spattering paint when you add a coat to the ranch house. Rub a little on any kind of threads -- from nuts and bolts to screws -- for easy-on-or-off or in-and-out, and to prevent corrosion and make seals watertight. Experiment a tad and you'll find even more uses for petroleum jelly. And that's the On The House tip for today.
